QuEST: A natural language interface to relational databases
Natural language interfaces to databases systems allow the user to use natural language to interrogate a database. Current systems mainly focus on simple queries but neglect nested queries, which are predominant in real cases. We present a NLIDB system, QUEST, which is able to cope with nested logic queries, without imposing any restrictions on the input query. QUEST outperforms a strong baseline system by 11% accuracy.
